can anybody help?
i was driving on the motorway at the weekend and i got a lot of vibration through the seat and wheel.
now driving about town i don't get any vibration, anybody got anyclues?

wheel balancing / tracking springs to mind, your alloys do they have the weights on the outside? if so this is bad, they should be on the inside and not be seen.

Wheel Wobble = Front wheel balancing / tracking / idle control arm

Seat or arse vibration = rear wheels not balanced / diff issues

What a load of old cobblers!

They can be on either, the important thing is that they are there.....some fitters only fit one set of weights!

Wheel balance is a favourite if the wobble is around the 70ish mark, also check the wishbone bushes to...

I think what Tunnie is referring to are the stick on weights! which are fitted on the inside rim

On the subject of noise, I found that with my old rears, down to the wear indicator, quite a lot of drumming / road noise.  New rears, wow...

Sorry, doesn't help with the vibration though.

I've had something like this several time before.......... if it's a light vibration through the seat it's a good time to check the UJ's on the prop shaft as they are starting to tighten up and will need to be replaced and as happened to me a while back the center bearing carrier on my Senattor started to break up and caused the same effect but i tended also to get a shudder when pulling out out of a junction but, i never had a steering shake with this
it's worth looking in this area as the Omega has the same set up

I was told that for alloys they should never be on the outside of the rim, as they were never designed for it. They should be weighted on the inside of the alloy.

When I got my Omega it had awful weights clipped to the outside edge of the rim, got horrible wheel wobble at 80. Took it to Vaux, who removed them.. and did it properly on the inside. Wheel perfect now at 80...

Also those weights on the outside of the rim, damage alloys. You have lead weights, clipped to alloy... which causes them to rust. Had it on my old Mondeo.

Of course I could be completely wrong as usual ...

You are.....the important thing about wheel balancing is:

A) They must be done correctly at multiple speeds and balance the wheel on both edges (important on wide wheels).....and the weights idealy should be as close to the edge as possible.

B) They must be the correct weights.

Tell me this, where are the inner weights fitte.....answer, normaly on the inner alloy rim!

In reality, stick on weights are a compromise as they are fitted a reasonable distance in from the edge of the wheel.....granted, they look better and on some facelift alloys there is no outer rim to fit clip on weights to anyway....plus alloy clip on weights tend to have a different fixing design to.

If yours were vibrating then it was either:

1) They were not correct in the first place

2) Soem thing ahd put the wheel out of balance....

Cheers Mark i stand correct yet again!  

When under the car, i noticed mine have weights that are actually on the wheel, and not clipped to the edge. I always assumed alloys should have them on the inside....

I have a feeling the weights were completely wrong when i got mine.

When I recently got a pair of tyres the wheel balance machine offered about 4 types of balance (i.e. different types of weight fitment).

I think these were something like:

1. clip on rim inner + clip on rim outer
2. clip on rim inner + stick on outer
3. Don't know
4. Don't know

The chap chose (2) for mine, which seemed sensible.
